Title:     Neutrino Production and Interaction Modeling for Long Baseline Neutrino Experiments

Abstract: Current long baseline neutrino experiments such as T2K measure the probabilities of a beam of muon neutrinos to oscillate to other neutrino flavors. These measurements rely on accurate knowledge of the neutrino beam composition at the production point and neutrino interaction rates. As T2K moves into the realm of precision oscillation measurements, reducing the uncertainties on the neutrino flux and cross section modeling is crucial for achieving our sensitivity goals. In T2K results presented at ICHEP 2012, we have already shown systematic uncertainties reduced to 10% (from 20% in previous results) using a combination of constraints from external experimental data and measurements from our near detectors. In this talk, I will discuss the efforts T2K has taken to reduce these uncertainties and prospects for further improvements. I will also consider future experiments such as the proposed
Tokai-to-HyperK experiment, and prospects for controlling systematic uncertainties at the level necessary to detect CP violation and precisely measure oscillation parameters.

Stimulants available 15 minutes before the talk.
